SHADE-HOLDER FOR LAMPS.

specification of Letters Patent. Patented Apr, 13, 1915.

Application filed February 24, 1914. Serial No. 820,401.

To all whom it may concern Be it known that 1, Henry E. BANDLOW, acitizen of the United States, and aresident of Ciicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Shade-Holders for Lamps; and I do hereby declare thatthe following is a full, clear, and exact descripti on thereof,reference being had to the accompanying drawings, and to the charactersof reference marked thereon, which form a part of this specification.

This invention relates to a novel shade holder or support for lamps, andthe invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claims.

Among the objects of the invention is to provide a shade holder arrangedto support the shade in such a manner as to permit the shade to adjustitself to the holder or support in its movements relatively thereto dueto expansion and contraction of the shade, so as to thereby avoidbreaking stresses being imposed on the glass or like material of theshade such as would tend to break the same.

A further object of the invention is to provide a shade holder which isso constructed and arranged relatively to the lamp frame as to reliablyhold the shade in place on the lamp without the necessity of usingholding screws or like devices which exert pressure on the shade in amanner tending to break the same during expansion and contractionthereof.

A further object of the invention is to provide a shade holder adaptableto lamps of the general character shown which may be readily applied tothe lamp and to the shade and one which does not detract from theappearance or design of the lamp.

Another object of the invention is to provide a shade holder which maybe made at small cost and which. occupies but little storage space inthe package in which same is shipped.

In the drawings :Figure 1 is a View partially in elevation and partiallvin section of a lamp and shade equipped with a holder embodying myinvention. Fig. 2 is a plan view of the holder. Fig. 3 is a sideelevation thereof, the dotted lines indicating the collapsed position ofthe holder Fig. 4 is a plan view of one of the members of the holderafter it has been blanked, but before it is formed. Fig. 5 is afragmentary view, showing a modification.

The lamp, embracing a base 10, the upright stem or generator tube 11,and the burner 12, may be made of any well known or approved form, andneed not be further described. 7

The shade 14: is a conventional shade, it comprising a lower curtain orh ood portion 15 which incloses the burner and an upper reduced neckportion 16 which is open at its top and is surrounded at its open topwith a narrow, inwardly extending, annular flange 17 to constitute ashoulder.

18 designates, as a whole, my improved shade holder which supports theshade on the lamp frame and holds it symmetrically relatively thereto.The holder 18 .is herein shown as supported directly on the upperportion of the casting of the burner 12, the casting being formed with aseat 19 to receive the same and the holder. It is fixed thereto in anysuitable manner, as by means of a screw 20 which extends downwardlythrough a central opening 21 of the holder and into a suitablyscrew-threaded opening in the burner casting. The holder consists of twolateral members composed of segmental rims 22, '22 curved concentricallyto the opening 21, and inwardly extending arms 23, 23 which are formedat their inner ends to constitute enlargements or heads 24, 24 that arerecessed at their adjacent margins to constitute the central opening 21.Said enlargements 2 1 of the arms 23 are formed to provide hinges bywhich the memhere are hinged together so as to swing vertically towardand from each other and to thereby enable the holder to be folded orcollapsed, as indicated, in dotted lines in Fig. 3, to facilitate theplacing and removal of the holder.

As herein shown the two members of the holder are interchangeable, eachbeing formed by the same cutting and forming dies. In Fig. 4 is shownthe form of the blank after it has been cut from sheet metal stock andbefore it has been formed up. As herein shown the enlargement or head 2of the arm of each member 23 is provided with a finger 25, located atone side ofthe longitudinal axis of the arm and parallel therewith, anda second finger 26 at the other side of the head and arranged at rightas most clearly shown in Figs. 2 and 3, and

said fingers 26 are bent downwardly to constitute stops to preventlateral separation of the members. The construction describedconstitutes a'simple and reliable means of hinging the members together,but, so far as the broader features of the invention are concerned, thehinge may be varied.

The arms 23, 23 are inclined downwardly and inwardly from the rimsegments 22 toward the heads 24: thereof so as to give to the assembledholder a dish form, as shown in Figs. 1 to 3. .The amount of the dishrequired will depend upon the distance the upper end of the shade issupported above the burner casting.

From an inspection of Fig. 1, it will be noted that the shade issupported from the holder in such manner that the shade is heldcentrally relatively to theburner below, and in suchmanner also that theexpansion andcontraction of the material of the shade is not underrestraint by reason of the holding engagement between the shade and theholder. Therefore, contraction and expansion of the shade has notendency'to break the shade.

An' advantage of making the holder in two parts which are hingedtogether in the manner described is that the holder may be,

readily applied to the lamp frame and shade andremoved therefrom. Thisis especially true where the neck of the shade assumes the form shown inFig. 1, wherein it is of smaller diameter at the lower end than at itsupper .end. Moreover, the holder may be made at relatively small costand may be packed in small compass for shipping. It will be noted thatthe two parts of the holder are rigidly ,heldrelatively to each otherand to the lamp frame by reason of the clamping action thereon due tothe flange 28 of the holder screw 20, the holder being clamped betweensaid flange and the seat 19.

As: far as is concerned the hinged feature of the holder this maybeadapted for engagement with an external shoulder 30 0f the shade orglobe3l, as shown in Fig. 5, the'holder 32 in this instance having aperipheral hooked ring 33 to engage under the shoulder or flange 30.

I claim as my invention 1. Means for supporting glass "and like rigidlamp shades of that kind composed of a' lower curtain portion tosurround the lamp burner and an upper restricted neck portion formedwith an internal shoulder, comprising, in combination with such shadeand a lamp frame within the shade and provided below the plane of saidshoulder with a holder seat, of a holder contained wholly within theshade and supported on said seat and provided with arms which extendoutwardly therefrom and formed at their outer ends with supportingsegments to engage said shoulder to support the shade symmetrically ofthe lamp frame.

2. A holder for glass and like rigid lamp shades of that kind composedof a lower curtain portion to surround the lamp burner and an upperrestricted neck portion formed with an internal shoulder, comprising, incombination with a lamp frame, a holder member seated on the lamp framewithin said neck portion, consisting of hinged portions provided withperipheral shade supporting rim segments to loosely engage and supportthe lamp shade.

3. A holder for lamp shades comprising two hinged members eachconsisting of a horizontally curved shade supporting segment and aninwardly extending arm, with the hinge constituting integral portions ofsaid arms.

4. A holder for lamp shades comprising two members, each consisting of ashade supporting rim segment and an inwardly extending arm, said armsbeing cut away at their inner ends to receive a fastening pin or screwand a hinge for connecting the arms together.

A holder for lamp shades comprising two members, each consisting of ashade supporting rim segment and an inwardly extending arm, said armsbeing cut away at their inner ends to receive a fastening pin or screwand a hinge for connecting the arms together, saidarms, inclininginwardly and downwardly toward said hinge, for the purpose set forth.

6. A holder for lamp shades comprising two members, each consisting ofan outer, horizontally curved shade supporting rim and an inwardlyextending arm, said arms being provided at their inner ends withintegral foldable hinge elements adapted to constitute cooperating hingeeyes and pintles to hinge the members together.

In testimony that I claim the foregoing as my invention I aflix mysignature, in the presence of two witnesses, this 10th .day of February,A. D. 1914. V
